Thank you for using NI-DAQ, version 7.2.

Your NI-DAQ software contains three Application Programming Interfaces (APIs), which are libraries of functions or VIs, attributes, and properties for creating applications for your device. These APIs are Traditional NI-DAQ, NI-DAQmx, NI-SWITCH.

If you do not know which API to program with, refer to Choosing the API to Use. To find out if your device is supported in an API, refer to Support in NI-DAQ 7.2. For additional information and known issues specific to Traditional NI-DAQ and NI-DAQmx, refer to the following:

• Traditional NI-DAQ Readme
• NI-DAQmx Known Issues

Choosing the API to Use

This section provides an overview of Traditional NI-DAQ, NI-DAQmx, and NI-SWITCH and includes information on choosing the right API for your device and application.

NI-DAQmx

NI-DAQmx is the latest NI-DAQ driver with new VIs and functions and development tools for programming measurement devices. Install and use NI-DAQmx if the following situations apply:

• You are using Windows 2000/NT/XP.
• You are using only device(s) supported by NI-DAQmx. Refer to Support in NI-DAQ 7.2 for a list of supported devices.
• If you are using NI application software, you must use LabVIEW, LabWindows/CVI, or Measurement Studio 7.x, or LabVIEW Real-Time version 7.1 or later.
• If you use one of the Measurement Studio .NET languages or a device supported only by NI-DAQmx, such as the NI PXI-4204, NI 4461, or NI 6509, you must use NI-DAQmx.

Traditional NI-DAQ

Traditional NI-DAQ is an upgrade of version 6.9.3 or earlier of NI-DAQ. Traditional NI-DAQ has the same VIs and functions and works the same way as NI-DAQ 6.9.3, except you can use Traditional NI-DAQ and NI-DAQmx on the same computer, and some hardware is no longer supported.

Install and use Traditional NI-DAQ if one of the following situations apply:

• You have a device that is not supported by NI-DAQmx, such as the AT E Series multifunction DAQ devices.
• You are upgrading from NI-DAQ 6.9.x and have existing applications that you do not want to port to NI-DAQmx now.
• You are using a version of LabVIEW, LabWindows/CVI, or Measurement Studio earlier than version 7.0.
• You are using Visual Basic 6.0.
• You are using the LabVIEW Real-Time Module for Macintosh.

NI-SWITCH

NI-SWITCH is an IVI-compliant switch instrument driver that supports all NI switch modules. NI-SWITCH has an interactive soft front panel for testing and troubleshooting switch applications. NI-SWITCH 2.0 and later requires you to install NI-DAQmx and NI-VISA 3.0.

Support in NI-DAQ 7.2

Version 7.2 of NI-DAQmx does not yet support the full line of NI measurement devices. The next few releases of NI-DAQ will add support for new and existing devices in NI-DAQmx, and will continue to include Traditional NI-DAQ.

Operating System Support

NI-DAQmx and Traditional NI-DAQ, version 7.2, and NI-SWITCH 2.2 support Windows 2000/NT/XP. NI-DAQ 7.x on Windows NT requires Service Pack 6 or later. If you are using Windows NT, make sure that you have installed Internet Explorer 5.0 on your computer for your help applications to work correctly. PCMCIA devices are not supported in Windows NT. NI-DAQmx 7.2 supports PharLap only with LabVIEW Real-Time 7.1. Measurement Studio requires Visual Studio .NET 2003, which requires Windows 2000/NT 4.0/XP. For operating system-specific installation instructions, use the Hardware Installation Wizard at ni.com/support/install.

To find and download an earlier version of NI-DAQ that supports other operating systems, refer to ni.com/downloads.

NI-DAQmx Known Issues

This section covers issues specific to NI-DAQmx.

Error 15550 When Installing Software to an NI PXI-8154RT Controller

When installing LabVIEW Real-Time 7.1 and NI-DAQmx software to an NI PXI-8145RT controller, MAX returns the following message:

"The operation could not be completed. Operation failed with error code: 15550. Possible reasons(s): The password you typed in was incorrect."

You must install the LabVIEW Real-Time 7.1 software to the RT target and then reboot the controller. You then can install all other necessary software to the RT target. Also, you cannot install NI-DAQmx if the NI PXI-8145RT controller is in Safe Mode.

Identically Named Tasks and Channels

Global tasks and channels should not have the same name. In languages other than English, NI-DAQ might allow you to create tasks and channels with the same name as long as the case is different (for instance, MyVoltageTaskÜ and MyVoltageTaskü). Using the same name, however, might prevent you from being able to programmatically select one of the tasks or channels. To avoid this overlap issue, make sure that each task and channel has a unique name (for instance, MyVoltageTask1 and MyVoltageTask2).

Aborting Single-Point Reads and Writes in LabVIEW

Single-point reads and writes do not respond to the Abort Execution button in LabVIEW.

DAQ Assistant Maximum Channel Count

The maximum number of channels you can have in a task created with the DAQ Assistant is 512 channels.

Switch Scanning Example Requires NI-DMM 2.2

The example Switch Scanning with DMM—Handshaking for LabVIEW was updated with NI-DMM 2.2. If you have an earlier version of NI-DMM installed, the VI is inoperable. To use the example with NI-DMM 2.1.2 or earlier, delete the AUX Trig 1 case from the case structure connected to Sample Trigger Source in the niDMM Configure Multi Point VI. NI-DMM 2.2 introduces a new enumerated value, AUX Trig 1, not available in NI-DMM 2.1.2 or earlier.
